Reading developmental history from X-chromosome mosaicism

Dr. Jesse Gillis, PhD
Associate Professor of Integrative Physiology
University of Toronto

X chromosome inactivation (XCI) balances sex chromosome dosage by randomly silencing one X-chromosome in each cell in the early embryo. Which chromosome is silenced is then clonally inherited through all subsequent cell divisions. This leaves each female mammal with a stable mosaic of cells expressing either the maternal or paternal X haplotype. This variability is propagated from early development and persists into adulthood. In this work, we discuss how this variability can be decoded across both individuals and cells to reveal developmental history and regulatory impacts. At the population level, the distribution of XCI skew across individuals reflects the number of cells present at the time of inactivation: more cells at that moment means less variance in the ratio among adults. By fitting models to population-scale XCI distributions across thousands of individuals and ten mammalian species, we show that embryonic cell counts at the time of lineage specification can be estimated from the variance itself, treating noise as the signal rather than the background. At the cellular level, the same mosaic structure allows us to perform within-individual comparisons that are unavailable through conventional approaches. Inferring X haplotype identity in single cells allows direct comparison of cells carrying different haplotypes within the same individual, holding genetic background and environment constant. This reveals structured patterns of regulatory variation that between-individual comparisons cannot resolve. Together, these research themes position XCI as a lens on both developmental history and regulatory variation, with the distribution of a stochastic mark across cells serving as a quantitative record of early decisions that cannot be directly observed.

Dr. Gillis is an expert in integrated neurophysiology at the Donnelly Centre in the University of Toronto. His lab focuses on characterizing the flow of information from cellular gene networks to whole organism phenotypes across species using functional genomics data, focused primarily on the brain.

Faculty Talks

Avoiding death in the gut: pre-adaptation through phase variation
Dr. Carolina Tropini, PhD
11:15 AM - 11:45 AM @ LSC 1
In the complex ecosystem of the human gut, physical forces profoundly shape the diverse consortium of microbes residing within. Despite advances in characterizing these microbial communities and their connections to health, the fundamental physical responses of this ecosystem remain understudied. Because physical perturbations are a hallmark of intestinal disease, understanding these responses is crucial for describing disease impacts and developing therapeutic interventions. Specifically, several gut diseases such as inflammatory bowel disease, celiac disease, or dietary intolerances alter the gut’s physical environment by increasing intestinal osmolality through malabsorption. In this project we investigate how commensal gut bacteria respond to laxative-induced osmotic stress using both in vitro experiments and gnotobiotic mouse models. We find that in the prominent gut commensal Bacteroides thetaiotaomicron, inversion of phase-variable DNA regions allows bacteria to rapidly adapt to environmental pressures. These inversions regulate a capsular polysaccharide locus as well as a major transcriptional regulator belonging to the CRP (cAMP receptor protein) family. Specifically, while these inversions do not improve growth rate in the perturbed environment, they strongly influence survival: cells that are not in a specific phase-variable configuration rapidly lose viability following osmotic shock, and surviving cells are enriched for a single phase state. Strikingly, this configuration is already dominant in vivo even in the absence of osmotic stress, suggesting that gut populations may be pre-adapted to withstand transient physical perturbations such as osmotic diarrhea. This work highlights the critical role of physical factors in microbial ecology, providing a foundation for the development of microbiota therapies informed by the gut’s physical landscape.
The Silent Genomes Project : Construction of and Indigenous governance over an Indigenous genetic variation reference database
Dr. Wyeth Wasserman, PhD
11:45 AM - 12:15 PM @ LSC 1
Rare disease diagnosis has been transformed by whole genome sequencing, but not equitably. Critical to the analysis is comparison to the background frequencies of genetic variants to focus on rare variants. Indigenous peoples in Canada and globally can faced delayed or blocked diagnosis due to the absence of adequate reference data. The lack of reference data can be attributed to a long history of abuses in Canada and globally. Modern approaches to genetics research focus on Indigenous Data Sovereignty, informed by the United Nations Declaration on the Rights of Indigenous Peoples, the concept of DNA on Loan, the calls of the Truth and Reconciliation Commission, and the OCAP and CARE principles. An Indigenous governance model was established for a reference genetic variation database over 7 years, shaped by discussions with Indigenous organizations and participating First Nations. The Indigenous Background Variant Library, released in 2025, emerged from the process and is now available to support rare disease diagnosis across Canada. The presentation will describe guiding principles, development of governance, technical implementation of the Nextflow processing pipelines and database, and the interface for users. Potential future work will be highlighted, including supporting other Indigenous reference genetics projects in Canada and globally.
Deep learning inference of universal dormancy pseudotime reveals the cellular targets of anti-cancer therapies
Dr. Adi Steif, PhD
11:15 AM - 11:45 AM @ LSC 2
Controlled exit from and re-entry into the cell cycle is essential for multi-cellular life, while aberrant quiescent and senescent cell states have been implicated in age-related diseases and cancer treatment evasion. Recent molecular and imaging studies suggest non-cycling cellular states exist along a continuum of deepening dormancy, whereby the probability of cell cycle re-entry decreases with distance from the restriction point. We trained a probabilistic deep-learning model that enables mapping of heterogeneous single cell transcriptomic datasets into an interpretable latent space that encodes a common "dormancy pseudotime". We demonstrate that our model enables robust inference of active cell cycle states, and validate in diverse biological contexts that the inferred location along dormancy pseudotime represents a continuum from quiescence to durably arrested states. Applying dormancy pseudotime inference to pre- and post-treatment time points from patients undergoing anti-cancer treatment, we uncover new insights into the distinct tumour cell dormancy states targeted by immune checkpoint inhibitors and platinum-taxane chemotherapy. Given the ubiquity of single cell transcriptomics, we anticipate that dormancy pseudotime analysis will be widely applied to shed new light on the complex interplay between cycling and non-cycling cellular states in health and disease.
Multiomics Data Integration: Benchmarking, Method Development, and Clinical Applications
Dr. Amrit Singh, PhD
11:45 AM - 12:15 PM @ LSC 2
Biomedical studies increasingly generate molecular, cellular, and clinical data from the same samples, creating new opportunities for disease prediction and biological discovery. In this talk, I will present our work across benchmarking, method development, and clinical application in multimodal data integration. I will introduce MESSI, a reproducible Nextflow-based benchmarking framework that standardizes preprocessing, supports interoperable R and Python workflows, and uses leakage-free nested cross-validation for rigorous model evaluation. I will also highlight DIABLO for biomarker discovery, caretMultimodal for late integration, and applications in neonatal studies, heart transplant rejection, heart failure, BCG vaccination, and single-cell multiomics. Together, these examples show how robust benchmarking and interpretable integration methods can help translate complex multimodal data into meaningful biological and clinical insights.
From grape to glass: multi-omics reveals terpenoid biosynthesis
Dr. Simone Castellarin, PhD
11:15 AM - 11:45 AM @ LSC 3
Terpenoids are key determinants of grape and wine aroma, yet the molecular bases of their accumulation in grapes remain largely unknown. We applied a multi-omics approach integrating genomics, transcriptomics, and metabolomics to dissect terpenoid biosynthesis across seven grapevine cultivars. Substantial variation in both free and glycosylated terpenoids distinguished high- and low-aroma cultivars. While copy number variation in terpene synthase (TPS) genes was observed, it did not explain differences in terpene accumulation. Instead, developmental regulation and cultivar-specific expression of TPS genes, particularly during ripening, emerged as primary drivers. Network analyses revealed complex relationships between transcripts and metabolites, highlighting limitations of correlation-based inference in this system. Functional characterization of selected TPS genes confirmed their roles in producing key aroma compounds that impact grape and wine aroma. Overall, our results indicate that terpenoid diversity in grapevine is shaped by an expanded and partially redundant TPS gene family under strong developmental and cultivar-dependent regulation.
Navigating Brobdingnag - questions we are asking in light of giant genomes
Dr. Tom Booker, PhD
11:45 AM - 12:15 PM @ LSC 3
If we want to understand the processes that shape biodiversity we need to understand the processes that shape genome evolution. Conifers represent an extremely interesting example of genome evolution. Conifer genomes are enormous, with typical haploid genome sizes >10Gbp, but tend to be highly conserved over time. Studying these massive genomes has helped us develop ideas about evolutionary biology in conifers, that also apply in other taxa. In this talk I’ll outline hypotheses that our group has developed by studying the massive genomes of conifers.

Dr. Cameron Herberts, PhD
Translational Medicine Scientist @ Natera
Dr. Herberts works closely with global academic and BioPharma collaborators to design, execute, and analyze correlative and ctDNA-guided interventional clinical trials, aiming to define how ctDNA can be incorporated into clinical management paradigms. He completed his BSc in Biophysics (2018) and PhD (2024) at The University of British Columbia. During his doctoral training with Dr. Alexander Wyatt in the Department of Urologic Sciences, he helped develop blood-based circulating tumour DNA (ctDNA) approaches for (epi)genomic biomarker characterization, supporting the integration of this new technology into routine clinical care for metastatic prostate cancer. He is now a Translational Medicine Scientist at Natera focusing on ctDNA clinical evidence generation across genitourinary cancers.
